The present inventionrelates to domestic cooking ranges and moreparticularly to an improved oil supply tank and support therefor.

The principal object of my invention is' the provision of an improvedoil'supply tank Iand support therefor-which is safe and convenient touse and which isecient in operation and durable in service. c

Other and furtherfobjects and advantages of my invention will becomeapparent from the following-description.

For a better understanding of the present invention and the manner inwhich the foregoing objects have been carried out, reference will nowvbe had to the accompanying drawings and t the -f following detailedlspecification in both of which like reference characters Idesignatecorreslzaondn ing parts throughout and in which,

Fig. 1 is a perspective View of a combination gas and oil kitchen rangewith the frontal door panels ajar;

Fig. 2 is a transverse sectional view through the fuel oil tank and istaken approximately on line 2--2 of Fig. 1; and

Fig. 3 is an enlarged'front elevational view partially in section and istaken on approximately line 3-3 of Fig. 2.

By referring to Fig. l the observer will note that the combination oiland gas range herein contemplated consists essentially of aconventionally rectangular enclosure having side walls II, each linedwith sheet metal with an intermediate lling of insulation material. Theback wall may be correspondingly constructed and provided with elementsto join with the side walls II and I2, after the manner of conventionalassembly methods, so that the three wall sections denne an overallrectangular enclosure resting upon a supporting base I5.

The top of the range is comprisedU of a gas burner plate sectiondesignated I1, and an oil burner plate section designated I8, the latterof rwhich includes the removable discs I9 and 2I which overlie the oilburner units so as to aiord accessibility thereat for occasional repair,replacement, clean-out, or emergency lighting.

The front panel whichY is coextensive with the range width isdesignated-24 in Fig. 1 and in its surface may be noted the oven opening25, the

storage and fuel tank opening 2B, .the broiler opening 21 and theservice opening 28 to the fuel oil valve apparatus. For aestheticreasons, panel 24 is recessed slightly or in other words, is situi atedin a plane behind the control panel 29 which 'carries the gas burnercontrol knobs 3l to 35, Fig.

., 1 claim (o1. 12s- 44) 2 l l, the oil burner control valve drum dials36 and 31, and the direct or starting damper control knob v38.Correspondingly', there are provided sectional door elements of athickness corresponding 'to this recess or difference in plane levels,for covering each ci the front panel openings, aforedescribed. Theseinclude the wing doors tI and 42, the oven door i3, andthe broiler door`44 which abut each other edgey to edge during closed position.

5 Attention will now be directed more particularl'y to the oil burnerfeatures of the present invention. A supply of fuel oil is carried in acylindrical closed tank 1I, Figs. 1, 2 and 3, which is supported in ahorizontal position upon a sheet metal saddle structure also referred toas a sump and designated 12. Thesump is a shallow open tank defined bythe end -walls 13 and 14 which have the curved nesting flanges 15conformto the transverse curvature of the tank 1I and the inwardly bentside walls 15 and 11 which together the tank 1I passes through openings8| in a cylindrical spring housing 82 when the Valve head 83 isdepressed by the tank projection 84 pressing against the spring 85 andthereby leaving an escape clearance where it otherwise engages the valveseat 86 of the flange tting 81.

As the quantity of fuel oil in the sump reservoir 12 becomes consumedand is withdrawn through the feed pipe 88, the level 19 will recede butto an extent only which will permit replacement air to enter the tank 1Ithrough the valve seat opening. The replacement air which bubblesthrough the supply of uid in tank 1I permits a portion of the uid toflow out through the same opening and raises the level 19 to itssealing-off condition as aforedescribed.

When the supply `o1 oil in tank 1I is exhausted the tank may be removedfor replenishment from its nested position on the sump 12 by rotatingcounter-clockwise as viewed in Fig. 3. This operation can be manipulatedwith the aid of the `pivoted handle 89 whereupon the threaded nipple 9|together with its carried valvefittings will clear the flared curvatureportion 92 especially provided for this purpose and the tank 1I maythereupon be withdrawn forwardly or towards the operator, Fig. 1. Theamount of fuel supply within the tank 1I may be continuously indicatedupon the loat recording dial 93 which is visible when the Wing door 42is ajar. To replenish the liquid fuel in the tank 1I the screw cap orfitting 81 may be removed by unscrewing from the nipple 9| andreplenishing fuel poured into the tank 1I until lled. After this the cap81 is restored. When the filling operation has been completed the valvehead 83 urged by its spring 85 will seal the opening by seating againstthe valve seat curvature 86 and the tank may be reinstalled 'byreversing the 'aforedescribed removal procedure, that is to say, byrotating clockwise instead of counter-clockwise until the flange tting81 abuts against the limit bracket 94 whereupon the head of valve 83will then again be aligned above the embodiment 84, permitting theliquid to flow downwardly into the sump until it attains its sealinglevel.

The fuel oil which is supplied through pipe 88 is conveyed rearwardly ofthe oven, flowing gravitationally whereat it is controlled hyY a of feedsupply Valves preferably of the `needle type which are contained withinthe tubular er1- closures 98 and 99 that encase the needle rods 41. Theupper ends of the needle red 4l carry the aforedescribed drum type dialheads 36 and `31. When the valves are Qnened the fluid snnnly frem theoil reservoir will be distributed to they burners to an extent or levelwhich corresponds with the fuel level in the sump 12.

While the present invention has been explained and described withreference to a spic embodiment it is to be understood nevertheless, thatnumerous modifications and variations may be incorporated Withoutdeparting from the essential spirit or scope thereof. It is accordinglynot intended to be limited for an understanding of the invention to thedetailed disclosure in aecompanying drawings,nor to the specic languagein the aforegoing description, but to be accorded instead a latitude` ofinterpretation as afforded by the hereinto appended Gleim.-

The invention claimed is:

In a kitchen range in which a frontal panel is provided with arearwardly extending fluid fuel storage aperture of predetermined widthdimensions, the combination with a sump tank oomprising a relativelyshallow horizontally disposed rectangular basin having fore and aftwalls with uppermost edees formed inte circular nesting flanges andinwardly eenvergine sidewalls which together with said fore and aftwalls form a seating perimetry for a cylindrical closure cover Vto saidsump tank, a bottom wall to said sump tank having a valve actuatingprotuberance with an inclined approach surface and a valve engagingabutment element, of a removable reserve liquid fuel supply storage tankof cylindrical conformity to coincide with the circular curvature ofsaid nestingv flanges and of length to overlie said fore and aft sumptank walls and thereby to constitute a closure cover to said sump tank,a protuberant valve housing jutting -axially of said storage tank andlocated longitudinally on its cylindrical wall in a position to registerwith said sump tank bottom wall protuberance and abutment element, 'aninwardly depressible spring loaded valveheadcontained in said valvehousing 'having a portion outwardly extending so as to. be engaged byand depressed by said bottom wall protuberance when said storage tank isretated while nested. in seid tere and dit supportine. flangesv ene ofsaid sinne tank side Wells remote from seid botten; Wellebntrnentelement being fenned wtn en intermediate aperture in transverseregistration with seid beidem Well abutment so that when said storagetank is reteted in its nesting denses seid valve housing may be passedclear of said sump tank side wall.
